You will need two 9-inch nonstick sauté pans for this recipe. In one pan sauté the sausage with the onion until almost browned. Add the garlic and continue to sauté until meat is browned and garlic is softened. In the other pan melt two tablespoons of butter. Add the tator tots to the pan and spread out in a single layer. Press them down into the pan and allow them to brown on one side for about two minutes. Shake the pan to keep the tots from sticking. Add the remaining butter, if necessary. Flip the tots and let them brown on the other side. In the pan with the sausage pour in the eggs. Using a spatula, lightly scramble the eggs into the sausage. Allow the eggs to cook through. Meanwhile heat your tortillas in a low oven or microwave. To assemble the tacos add some of the tator tots to the tortilla and then some of the sausage and egg mixture. Top with salsa & grated cheese.
